This paper highlights two case studies of manufacturers that have replaced, or done studies to replace, stainless steel with electroless nickel-plated mild steel. In both cases, cost savings could be realized while maintaining or improving product quality.
Internal stress exists in electroplated and chemically applied metallic coatings. This paper reviews the test procedures for measuring deposit stress and the formulas used to calculate stress values. Many formulas used require modification to obtain actual internal stress values. Errors in this regard are examined and common mistakes are explained.
Assessment of Safer Polysulfide and Polythioether Sealant Removers for Aerospace/Defense Industry Applications
This assessment identifies and evaluates potentially safer alternatives for sealant removal applications. The sealant removal performance of the alternatives was evaluated using a designed experiment.

A Comparative Study of Gamma-Phase Zinc-Nickel Deposits Electroplated from Various Alkaline and Acid Systems
Sacrificial anodic coatings, specifically zinc deposits, have provided corrosion protection to components and parts across many industries, with an increasing demand in the automotive and industrial sectors. Today, typical sacrificial applications for fasteners, fuel systems, braking systems and drive assemblies require higher corrosion performance from anodic coatings. Electrochemical alloys can be designed to provide the highest corrosion potentials to meet these increased demands.

Plastics are replacing metals in the manufacture of many parts, and quite often there is a need for metallic coatings on the plastics and other non-conductors. This paper will describe new processes of preparing ABS plastic substrates for subsequent metallization.
This paper will introduce an advanced alternative to Pb and Cd-free electroless nickel processes, which is completely free of toxic heavy metal (THM) stabilizers. The process and deposit characteristics will be discussed and compared to the traditionally Pb stabilized electroless nickel.

This paper describes the successful electroless co-deposition of tungsten within a nickel-phosphorus matrix to yield several advantageous properties.
The Tribology of Contact Finishes for Electronic Connectors Part II: The Effects of Underplate, Topography and Lubrication
This paper is an expanded treatment of the second part of the William Blum Lecture Dr. Antler presented at Sur/Fin 1988 by Dr. Morton Antler. Subjects covered include substrate and lubrication effects on the tribology of contact finishes.
This paper is an expanded treatment of the first part of the William Blum Lecture presented at SUR/FIN 1988 in Los Angeles by Dr. Morton Antler, 1987 AESF Scientific Achievement Award recipient. The subjects covered include friction, mechanical wear, fretting corrosion and frictional polymerization—all vital processes that affect the performance of contact finishes in electronic connectors.
